Gas One propane regulator 2-stage auto changeover — dual-tank with two 12in braided pigtails, stainless, 190,000 BTU

If you run appliances, heaters, or cooking gear from two propane cylinders in an RV, van, or trailer, a reliable auto changeover regulator removes the need to manually swap tanks mid-journey. The Gas One unit is a factory-set, two-stage regulator built for dual-tank systems and designed to maintain steady pressure while allowing one tank to be removed and replaced without cutting off fuel flow. Constructed from rust-resistant stainless components and supplied with two braided 12" pigtail hoses, it’s rated for 190,000 BTU to handle typical RV loads.

How does the auto changeover feature work while I’m traveling?

The regulator continuously monitors inlet pressure from both tanks and automatically switches to the reserve when the primary tank’s pressure drops below the factory set threshold. Switching happens without manual intervention, so appliances stay lit and systems keep running during transitions.

• Automatic detection of low primary tank pressure
• Seamless transfer to reserve tank with no flame-out
• Factory set at 11" water column for consistent switching behavior
• Designed for in-use tank replacement without shutting down supply

What fittings, hoses, and performance specs should I expect?

This two-stage regulator works with common RV plumbing and is rated to supply substantial loads up to 190,000 BTU. It accepts 48" hose systems and arrives with two 12" braided stainless-steel pigtails for secure tank connections.

• Rated capacity: 190,000 BTU
• Pigtail hoses: two braided 12" lines included
• Compatible hose length: suitable for 48" hose assemblies
• Inlet/outlet sizes: 1/4" SAE inverted flare inlets and 3/8" NPT female outlet

Is the regulator durable and safe for outdoor/road use?

Gas One built this regulator with corrosion-resistant stainless materials and robust finishes to withstand outdoor exposure and the vibrations that come with vehicle travel. It’s a two-stage design, which provides steadier downstream pressure than single-stage options and helps protect appliances and piping from pressure fluctuations.

• Heavy-duty rustproof stainless-steel construction
• Two-stage regulation for stable downstream pressure
• Braided pigtails reduce kinks and improve abrasion resistance
• Factory set for predictable, safe changeover performance

Who is this for? Adventurers and full-time travelers who use dual propane cylinders in RVs, camper vans, trailers, or mobile work rigs and want uninterrupted fuel during tank swaps will benefit most. Installers, fleet managers, and DIYers replacing a manual switch or aging regulator will appreciate the straightforward fittings and included pigtails. If you need a compact, auto-switching regulator rated for high BTU loads and built to resist corrosion and road conditions, this Gas One model is designed for that role.
